Distribution and diversity of begomoviruses in tomato and sweet pepper plants in Costa Rica

摘要: Begomoviruses (genus Begomovirus, family Geminiviridae) have emerged as important plant pathogens in tropical and subtropical regions worldwide. Although these viruses were reported during the 1970s Costa Rica, they are still poorly known. Therefore, objective of this study was to analyse diversity distribution begomoviruses commercial tomato sweet pepper fields from different agricultural production systems major growing Rica. A total 651 plants randomly sampled greenhouses open field crops 2011 2012 three geographical locations. The bipartite Tomato yellow mottle virus, leaf curl Sinaloa virus Pepper golden mosaic monopartite begomovirus detected collected samples. complete genome isolates each species cloned sequenced. frequency detection four analysed samples ranged 0 9%, presence, prevalent varied largely according location, host (tomato pepper), system (greenhouses or fields). An association between region observed suggesting that Rica heterogeneity on climate, topography might influence country. broader survey needs be conducted confirm it, although preliminary results may contribute management
